Understanding Sex and Your Brain

Understanding how sex affects your brain can improve your roll in the hay, and it may also shed light on other parts of your health, says Barry R. Komisaruk, PhD, distinguished professor of psychology at Rutgers University in Newark, New Jersey. It's not the easiest subject to study—test subjects might have to masturbate in an MRI machine—so research is still developing. But scientists are starting to unravel the mystery. Here's what we know so far about your brain on sex.

Sex makes us feel good

That's why we want it, like it, and spend so much time hunting for mates. The pleasure we get from sex is largely due to the release of dopamine, a neurotransmitter that activates the reward center of the brain. Dopamine is also one of the chemicals responsible for the high people get on certain drugs. "Taking cocaine and having sex don't feel exactly the same, but they do involve the same [brain] regions as well as different regions of the brain," says Timothy Fong, MD, associate professor of psychiatry at UCLA's David Geffen School of Medicine. Caffeine, nicotine, and chocolate also tickle the reward center, says Komisaruk.

Sex can act like an antidepressant

A 2002 study out of the University at Albany looked at 300 women and found that those who had sexwithout a condomhad fewer depressive symptoms than women who did use a condom. The researchers hypothesized that various compounds in semen, including estrogen and prostaglandin, have antidepressant properties, which are then absorbed into the body after sex. (They corrected for other things that might affect both mood andcondom use, such as being in a serious relationship or use of oral contraceptives.) This is good news for anyone who is in a committed relationship, but if you're still playing the field, then you shouldn't give up condoms. There are other ways to boost mood, but really no other way to prevent sexually transmitted diseases.

Sex can (sometimes) be a downer

Those feel-good chemicals may be going full blast during the act, but after? According to researchers, there is such a thing as post-sex blues (technical term: postcoital dysphoria). About one-third of the women participating in one study reported having experiencedsadness after sex at some point in time. While it's possible that regret or feeling coerced might be the reason why, researchers can't explain the connection at this point for sure.

Sex relieves pain

Don't skip sex when you have a headache. Research shows that doing the deed may relieve your symptoms. In a 2013 German study, 60% of participants who had migraines and 30% of cluster-headache sufferers who had sex during a headache episode reported partial or total relief. Other studies have found that women who stimulated an area of the G spot had an elevation in pain threshold. "It took greater pain stimulus for them to feel the pain," says Beverly Whipple, PhD, a professor emerita at Rutgers University who has conducted some research on the topic. Whipple didn't study why this was so, but other researchers have attributed the effect to oxytocin, the so-called bonding hormone that helps mothers and babies bond and which also has pain-relieving properties.

Sex can wipe your memory clean

Each year, fewer than 7 people per 100,000 experience "global transient amnesia," a sudden but temporary loss of memory that can't be attributed to any other neurological condition. The condition can be brought on byvigorous sex, as well as emotional stress, pain, minor head injuries, medical procedures, and jumping into hot or cold water. Theforgetfulness can last a few minutes or a few hours. During an episode, a person cannot form new memories or remember very recent events. Fortunately, there seem to be no lasting effects.

Sex calms you down

The same study that linked frequent sex to a brain boost in rats also found that the rats were less stressed. This works for humans, too. One study found that people who'd just had sexual intercourse had better responses to stressful situations like public speaking than people who had not, or who had engaged in other types of sexual activity. How did sex ease stress? In this case, by lowering blood pressure.
